Any bird caught up parapara leaves needs immediate attention, especially fantails or grey warblers as they can't go long periods without food.
If you find birds caught up in the tree, do not cut any feathers. Cut off the branch/twig and bring the bird into us (no need to ring first), or to your nearest bird rescue centre or vet after hours.
The tree does not need to be cut down or destroyed. Just cut the sticky pods off, collect them off the ground, and place them in a bag. Alternatively, remove the pods from the tree after flowering, or cover the whole tree in bird netting during flowering.
Garden centres sell these trees as ornamental garden/house plants, but they often don't have display warnings about the possible dangers to wildlife. But this may help to make an informed decision as to an appropriate place to plant the tree.
